This is a rotary switch for a Strat or similar 3 pickup guitar. In addition to the usual 5 switch positions (N, N+M, M, M+B, B) it also adds the neck and bridge pickup option (AKA GIlmour Mod)

Each kit is individually handwired in our workshop and "flying leads" are fitted so you dont have to solder to the individual pins and included are wiring diagrams and soldering guide
